MOLD.

Application filed September 22, 1923. Serial No. 664,227.

constructed that the size and thickness of the concrete cross formed thereby may be readily altered or the lengths of the arms thereof changed as may be desired.

A still further object of the invention is to provide a device of this character which may be readily and cheaply produced, which will be durable and efiicient in service and a general improvement in the art.

These and other objects I attain by the construction and arrangement shown in the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein:

Figure 1 is a plan view showing a mold constructed in accordance with my invention;

Figure 2 is an enlarged sectional view taken on the line 22 of Figure 1;

Figure 3 is a plan view showing the mold in use for forming slabs;

Figures 1, 5 and 6 are enlarged plan views of alternative end members;

Figure 7 is an enlarged detail sectional View on the line 7-7 of Figure 1;

Figure 8 shows the arrangement of a primary or mother mold preparatory to building up a cross mold of the desired thickness; and

Figure 9 is a section on the line 9-9 of Figure 8.

Referring now more particularly to the drawings, the numeral 10 indicates a support or table having a fiat upper surface upon which the mold proper is arranged. The mold consists of a section 11 for forming the vertical stem of the cross and a section 12 for forming the cross arm thereof. Each of these sections is formed of a pair of spaced side members 13 and since these side members are of similar construction upon the cross with the exception of the length thereof, but one thereof will be herein described.

Each side member proper is divided into two sections A and B arranged at opposite sides of the center of the crossing point of the main'stem 11 and arm 12. Each section is formed of a lower layer 14 and an upper layer 15, the inner edges of which are oppositely beveled as at- 14? and 15 or otherwise shaped to provide a desired corner mediate layers 16 forming spacing elements determining the thickness of the cross. The meeting ends of the sections of the arm and main stem sections are beveled as indicated at 17 to provide a joint therebetween. Other types of joints may be provided if desired. Sections 141, 15 and 16 are secured together and to the table by means of securing elements 18 and it will be obviand a plurality of interi ous that by varying the length of the sections 13 and the space between the adjacent faces thereof, the width and length of the arms of the cross may be regulated as desired.

It will be seen that the sections 13 in opposition provide with the table 10 the desired cross section of a cross formed by depositing concrete between the same. In conjunction with these sections, I provide end members 19 which are similarly in cross sec tion to the cross section of the cross, being formed so that they inter-fit at their side edges with the mold sections 13 and thereby fill the space therebetween. These sections are secured in desired adjusted position in any suitable manner, screws being employed in the present illustration. Certain of these end members have both ends thereof flat. At C I have illustrated end members, both ends of which are squared, at D and end member, one end of which is square and the other end of which is formed to provide a point at the end of the cross and at E, F and G. I have illustrated end members, both ends of which are formed with different types of end surface and which are interchangeable with the blocks C and D in the formation-of the cross. These end members are preferably laminated as in the construction of the sections 13 so that a desired thickness of the cross may be effected, in conjunction with any desired width.

It will, of course, be understood that different widths of end members must be employed with different widths of crosses. I further jprov'ide a name plate board 20 which'm'aybe secured upon thesurface of the table therein at the intersection of the arms and which is provided "with {grooves 21 in which may be slid lettering forming dies 22 to provide upon a completed cross the name, dates and the like. I

It will be seen that "by adjusting 'the widths of the arms and placing the end members'in the proper position the desired width and length may be obtained and that by placing a plate 20 in position with the desired insignia thereon, a complete "cross may-be produced at'a single'operation. In

the formation of the cross, if desired,"reinforcing elements 23 may be introduced into the material thereof. It will further be seen that if it'is desired to produce simplya column, this may be effected by'simply moving the eiidblooks C to'a point Where they align with the edges of't he sections'l3'of the vertica'l'member of the cross, "subsequent to whi'chby an adjustmerit of the end member C operating between'the sections 13 of the vertiral'se'ction l1 -a'ndtheblock D or corresponding blocks, the length of the column may be determined.

The method of employing the mold is best shown in Figure 8 in which figure I have'shown a mold each of the side sections of which is'composed, of a singlelayer,

on'certain of these side sections the second layer having been superimposed. It will be "seen that each separate layer of itself forms a mold and that adesired number-of the'molds are combined to produce the desired thickness ofthe cross. Thefirstflaye'r or mold might be termed a" mother" mold or form since it is only necessary in assembling the completed mold tojproperly position this first mold. After this mold is .placed tl'ie remaining mold can beplace'dthereon with thebolt receiving o'penin'g thereof in alignment'withthe first moldan'd their proper positioning-is assured. In "many instances the'production of a thin slab cross is desired andin such instancesa single layer -or'm o-l'd will often suffice.

A mold of 'theabjove character may be very cheaply produced since the elements thereof may be formed of wood'and'niay all be formed by operations "easily performed at the ordinary planing mill. Such a mold is furthermore veryreadily assembled and disassembled 'andis capable-of a wide range of use impossible with the ordinary-form of mold provided for this purnose. It will be observed that certain changes and modifications'may be made in the construction of the mold as hereinbefore 'nally of their whereby to adjust thelen'gth of eitherthe vertical or cross member of the produced cross.

set forth without in any manner departing from -the spirit of my invention and I accordingly do'not limit'myself to such specific structure except as hereinafter claimed.

'What is claimed is 1. A. mold for forming cruciform concrete sti uctures comprising vertical and cross arm members, each formed in opposed sections "of laminated materials and end sections slidable between said side sections to adjust ipose'd laminated sections arranged upon the support and combining therewith to produce a desired cross sectional area, each of said s de sect1ons being ad ustable upon the 'supportand variable as to depth, and end members interfitting with the opposed edges of the side sections and combining therewith'and'with said support to form a mold having an open top.

3. In moulding apparatus, a support, 0p-

'posed laminated sections arranged upon the 'su'pport'and combining therewith to produce a desired cross sectional area, each of said side sections being adjustable upon the support and variable as to depth, and end members interfitting with the opposed edges of the side'sections and combining therewith and with sald support to form a mold havin'gan opentop, eachof said endsections being lammated and having the sections thereof secured togeth'er'b-y removable securing elements.

4. In mold, a support, side and end r-sections re's'ting thereon, each of said side sections comprisingan upper section and a lower section having their inner edges formed to provide a desired corner upon the moulded structure and intermediate sections 'o'f material to regulate the thickness of the formed structure, said end sections conforming along their "side edges to the shaping of the opposed edges "of the "-sidesections and interfitti'ng therewith.

5. In a mo'l'd, si'cle' sections arranged to define -a cross,each of said side sections bemg variablefas to thickness and end sections coacting with said *side 'SQCtlODS and interfitt-ing with opposed faces thereofitoclose the ends of the cross members, said end members being adjustable longitudirespective side members In testimony whereof I hereunto afiix my "HARVEY L.
